I m a 27 year old female. I finished eating one day and had some pains in my left side. I didn t think much of it, assuming it was gas. But, hours later the pain kept getting worse! Now, when I lay down, it s very painful when I take in a deep breath. The pain is on my left side, between my hip & belly button. What could it be? Is there anything I can take over the counter to help? I already took pepto-bismul & ibuprofen, which didn t help at all.
